SUMPRODUCT breakdown by date

[Guest]

I'm currently using the formula below to breake it down by month but I also
need to have it breakdown those months by year.

SUMPRODUCT(--(MONTH(Sheet!A1:A10)=1),--(Sheet!B1:B10=Sheet1!C1:C10),Sheet1B1:B10)

This formula compares two columns and if those columns have the same data
for the same month then it returns the sum of the data. The only problem is
is does not distingush between year, which I need it to do so.

Any help is appreciated.

Hi


SUMPRODUCT(--(TEXT(Sheet!A1:A10,"yyyy.mm")="2006.01"),--(Sheet!B1:B10=Sheet1!C1:C10),Sheet1B1:B10)

This keeps returning zero... does the date in column A have to be in the
format "yyyy.mm"?

SUMPRODUCT(--(YEAR(Sheet!A1:A10)=2005),(--(MONTH(Sheet!A1:A10)=1),--(Sheet!B
1:B10=Sheet1!C1:C10),Sheet1B1:B10)

is an alternative

No. It simply must be in any valid date format. I just checked to be sure,
and it even worked when instead dates in column A were date strings (column
A formatted as text).

PS. To check, is a date in valid format, change the cell format to General -
the date must be displayed as number now (p.e. todays date will be displayed
as 38741)
